Allopurinol therapy in man interferes with pyrimidine biosynthesis de novo by inhibition of one or both of the two enzymes, orotate phosphoribosyltransferase (OPRT) and orotidylic decarboxylase (ODC), responsible for the conversion of orotic acid to uridine-5'-monophosphate. Inhibition of this pathway in vivo is followed in 1-3 wk by an increase in the activity of both of these enzymes in eryth...
The presence of Trypanosoma cruzi in chronic chagasic patients with negative xenodiagnosis (XD) after 6 years following completion of therapy with either itraconazole or allopurinol was assessed by polymerase chain reaction (PCR) and hybridization assays. A 330-bp DNA fragment amplified from the hypervariable regions of T. cruzi kinetoplastid minicircles was hybridized with total 32P-labeled ki...
INTRODUCTION Thiopurine therapy is often discontinued in inflammatory bowel disease (IBD) patients. The xanthine oxidase (XO) inhibitor allopurinol has previously shown to enhance thiopurine efficacy and to prevent adverse reactions, the mechanism of this beneficial interaction is not completely clarified. The aim of this study is to observe possible effects of allopurinol and low-dose thiopuri...
Standard therapy in the United States for malignancy-associated hyperuricemia consists of hydration, alkalinization, and allopurinol. Urate oxidase catalyzes the enzymatic oxidation of uric acid to a 5 times increased urine soluble product, allantoin. Rasburicase is a new recombinant form of urate oxidase available for clinical evaluation. This multicenter randomized trial compared allopurinol ...
OBJECTIVES To assess the efficacy and tolerability of lesinurad, an oral selective uric acid reabsorption inhibitor, in combination with allopurinol versus allopurinol alone in patients with gout and an inadequate response to allopurinol. METHODS Patients (N=227) with an inadequate response to allopurinol, defined as serum urate (sUA) ≥6 mg/dL on ≥2 occasions ≥2 weeks apart despite ≥6 weeks o...
background: pentavalent antimonials are still the first choice treatment for leishmaniasis, but with low efficacy and resistance is emerging. in the present study, the effect of meglumine antimoniate (ma, glucantime) combined with paromomy-cin, miltefosine or allopurinol on in vitro susceptibility of leishmania tropica resistant isolate was evaluated. method : the drugs were obtained from comme...
INTRODUCTION Allopurinol hypersensitivity syndrome is an idiosyncratic drug reaction characterised by an acute and severe multiorgan disease. It usually begins 2 to 6 weeks after starting allopurinol. The most important and critical characteristics are the presence of visceral involvement and haematological abnormalities; hepatitis, interstitial nephritis and eosinophilia are most frequently se...
background it has been reported that systemic administration of allopurinol improves cell survival. this study was aimed to evaluate effects of allopurinol on skin flaps in dogs. methods twenty dogs underwent one skin flap surgery with a 2-week interval. the first procedure was performed according to the standard protocols. the second phase was started by a 1-week pretreatment with allopurinol....
OBJECTIVE Arhalofenate is a novel antiinflammatory uricosuric agent. The objective of this study was to evaluate its antiflare activity in patients with gout. METHODS This was a 12-week, randomized, double-blind, controlled phase IIb study. Eligible patients had had ≥3 flares of gout during the previous year, had discontinued urate-lowering therapy and colchicine, and had a serum uric acid (U...
